MECHANISM FOR- TRANSMITTING POWER- FOR PUMPING PURPOSES.

Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed December 8. 1908 Serial No. 466,505.

To all whom it may concern: F Be it'known that I, JAMas A. BROWN citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Mechanismfor Transmitting Power for Pumping Purposes, of which the following is a specification.

This invention relates to pumps of thattype adapted to be operated either manually or by motive power, and it relates more particularly to an attachment in the nature of a transmission gear adapted to be applied to an ordinary hand pump whereby the pistonrod thereof may be operated by a motor.

The invention has for one of its objects to improve and simplify the construction and operation of power transmitting mechanisms of this character so as to be comparatively simple and inexpensive to manufacture', reliable and efficient in use, and so designed as to be readily applied to pumps already in use.

Another object of the invention is the provision. of a power-transmitting mechanism which is mounted on the pump barrel adjacent the base thereof and including a crank shaft operatively connected with the piston rod of the pump and driven by a worm ear.

With these objects in view and others, as

will appear as the description proceeds, the

invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate onecmbodiment of the invention, Figure 1 is a perspective view of a pump equipped with the improved power transmitting attachment. Fig. 2 is an enlarged vertical section on line 2-2, Fig. 3. Fig. 3 is a horizontal section on line 3S, Fig. 2.

. Fig. 4 is a vertical section on line ll,

Fig. 2.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawings, A. designates the standard or barrel of the pump, which is supported by the usual base or socket piece 1 in upright position, and on theupper end thereof is a guide bracket 2 having a bearing 3 in which the piston rod 4: reciprocates, and on the bracket is a link 5 supporting the handle or lever 6 for manuallyoperating the pump, the handle being preferably detached from the piston rod when the power transmitting mechanism is -in use. The pump thus shown and described is of ordinary construction and .the

sign or altering the construction of the orally by B is mounted wholly on the pump whereby the latter constitutes a supportand the parts thereof are compactly arranged andsubstantially constructed. The attachthe pump.

A sleeve 7 composed of two parts a and b embraces the barrel of the pump and is secured thereto by bolts 8 passing through opposed flanges 9 on the two parts of the sleeve. The part a of the sleeve has a horizontally-extending'bracket 10 which isoifset from the center of the sleeve and is formed with spaced bearings. 11 in which rotates a horizontal shaft 12 that is equipped witha Worm 13 disposed between the bearings, the latter having linings 4 of babbitt or the like. posed approximately in tangential relation to the barrel of the pump, and mounted above the same is a transversely-extending horizontal shaft 15 that carries a gear 1'6 which meshes with the thread of the Worm or screw 13 .to be driven by the latter. Disposed around the gear wheel l6-is a casing or hood 17 secured by bolts 18 to the hearings of the bracket 10, the said hood cooperating with the bracket to form a housing for the worm gearing. The hood or casforms the bearing for the shaft 15, he

ends for receiving crank disks 19 which are equidistant-1y spaced from a plane passing centrally hrough the pump in direction parallel with 'the worm shaft, as will carried by one of the disks 19 and is in the form of a hollow drum haying teeth extending around its periphery, said drum projecting into the casing or hood 1'? which is i open at one side for receiving it.

attachment is so, designed as to be readily appl ed thereto without changing the de,-,

mentis applied and removed as a unit from" This shaft is dis-.

pump. The attachment designated gen ing 17 has a tubular member 18 which shaft projecting out of the bearing at both be evident from Fig. 3. The gear .16 is pump is to be operated by hand.

For attaching the crank disks with the pump rod l, a cross head 20 is secured to the latter which has a sleeve 21 through which the pump rod extends, and passing through the sleeve and pump rod is a detachable pin 22 which is removed when the \Vhen the pin is removed, the pump'rod may be reci rocated loosely through the sleeve, the later then acting as a guide. Projecting from opposite sides of the sleeve are trunni'ons 23 to which the upper ends of the connecting rods 24 are fastened. The pump' handle 6 connects with the piston rod at a point between the bearing 3 of the bracket 2 and the base of the latter, while the cross head is connected with the'piston rod at a point above the bracket; The lower ends of the connectingrods 24, which extend down-.

wag'dly alongopposite sides of the pump, are attached to crank pins 25 which extend outwardlyfrom the outer faces of the crank disks 19 said crank ins bein arran ed inv alinement so that the connecting rods will reciprocate in unison.

Power 15 applied to the worm shaft 111 i any suitable manner, as for instance, by a belt and pulley device connected with an electric or' other motor, and for this purpose, the worm shaft extends through the outer bearing and is equipped with a pulley 26. When the pump is to be operated by the motor, the handle is preferably detached and the cross'head connected with the pump 10d. As the pulley is rotated by the application ofpower, the worm turns the gear 16 on the crankshaft, which, in turn, imparts, longitudinal movement to the connecting rods 24 in oppositedirections for reciprocating'the pump rod; It will thus be seen that the pump can be readily changed for operation either manually or by motive power.

By connectingthe cross head of the rods or pitmen 24 to the pump rod above the connection of the handle 6 to the pump rod, both friction and side strain is reduced through a reduction of the ratio between the length of the stroke and the length of the pitmen, besides the added convenience in being able to operate the pump by power without removing the handle which is used for hand pumping. By mounting the power transmitting mechanism as a whole upon the pump barrel, and making the two a unit, it overcomes any tendency of the pump to shunt the strain put upon' it by the power transmitting mechanism. There is also an advantage in setting'and adjusting the pitmen. The spacing of the crank disks equi-distantly from a vertical line passing centrally through the-pump barrel (Figs. 8 and 4) equalizes the strain upon the crank pins and pitmen and between the crank pins and cross head, and prevents any pump barrel and the From the foregoing description, taken in connection with the accompanylng drawings, the advantages of the construction and of the operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention,

together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative, and

that such changes may be made when desired as are within the scope of the claims appended hereto.
